Can I Use One MMSI Number for Multiple VHF or AIS Devices on my Boat?
Every vessel operating a VHF radio or an AIS transceiver will need a unique Maritime Mobile Service Identity (MMSI) number. If a vessel has multiple VHF and/or AIS devices, only one MMSI number will be needed and entered into each unit. This number is associated to the vessel rather than the devices.
If using a VHF 100, 200, 300, or 300 AIS, review the Related Content.
If using an AIS 600, review the Related Content.
